Accesorios de latón roscados

NAFCO es un fabricante y proveedor de accesorios de latón roscado de calidad en China, los accesorios de latón roscado están hechos de latón forjado y producidos con máquinas CNC de alta precisión, no solo precisas en dimensiones sino también estables y confiables en rendimiento. Los accesorios de rosca NAFCO ofrecen varios modelos y tamaños para seleccionar.

鈥� Disponible en roscas BSP, NPT

Se requieren accesorios de latón roscados según las aplicaciones y los tipos de tubería, normalmente se utilizan en sistemas de media y baja presión, presiones de trabajo inferiores a PN16. Generalmente roscas BSP para el mercado europeo, NPT para el mercado norteamericano, depende de los tipos de rosca de su sistema de tuberías. El color de latón en bruto, el niquelado y el cromado son los tratamientos superficiales más utilizados para accesorios de latón roscados. El enchapado ayuda a proteger los accesorios de latón roscados del oxígeno y se ven brillantes.

1. Before installing threaded brass fittings, clean and remove any objects from the pipes (in particular bits of sealing and metal), which could obstruct and block the threaded brass fittings.

2. Ensure that both connecting pipes either side of the threaded  (upstream and downstream) are aligned (if they are not the brass fittings may not work correctly).

3. Make sure that the two sections of the pipe (upstream and downstream) match, the brass fittings will not absorb any gaps. Any distortions in the pipes may affect the tightness of the connection, the working of the valve and can even cause a rupture.

There are three frequently brass materials for European market, HPb57-3 threaded brass fittings, CW614N threaded brass fittings and CW617N threaded brass fittings.

CW617N brass has better physical property to stand higher working pressure and temperature, more importantly the Pb percentage share is less than 2.5% and applicable for drinking water systems, good for environment and people鈥檚 health.

CW614N Brass is also popularly used because of similar compositions and lower costs, suitable for those applications without much environmental requirements.

Threaded brass fittings are easier than brass valves to produce, it will not require assemble:

1. Brass raw materials are bought from local suppliers in forms of brass bars.

2. Brass bars are cut into smaller pieces with different sizes according to order requirements

3. Some types threaded brass fittings are directly machined from brass bars; some of them needs hot forging to make rough bodies.

4. The rough threaded brass fittings bodies are trimmed and cut off unnecessary parts.

6. The rough threaded brass fittings are machined by CNC machinery for threads and dimensions.

7. The machined  threaded brass fittings bodies are nickel- or chrome-plated.

8. The threaded brass fittings are ready for delivery after final finished goods quality inspection.

Threaded brass fittings packing is very important for safe transport and brand appearance.

We pack threaded brass fittings in small inner boxes, then put into outer cartons, finally load in wooden pallets.

It will protect the goods well and can avoid damages and wet.

We also pack as per customers' OEM designs.

Our test laboratory equips with various devices for threaded brass fittings quality inspect and control, as well as new product development.

Equipment include material spectrometer analyzer, flow rate tester, torque tester, body resistance tester, endurance tester, high-low temperature tester.

These equipment enable us to analyze threaded brass fittings material compositions and type tests according to related standards, ensure our threaded brass fittings are correctly designed and produced.
